Closing. You haven't provided what $val["id"] is. I am guessing it is an integer (Player::getId()). It is supposed be the player's name (string).

[smlrrlms]

...
$this->players=array();
...
$this->players[$event->getPlayer()->getName()]=array("id"=>$event->getPlayer()->getName());
...
if($this->gameStatus==0)
        {
            $i=0;
            foreach($this->players as $key=>$val)
            {
                $i++;
                $p=$this->getServer()->getPlayer($val["id"]);
                //echo($i."\n");
                $this->getServer()->loadLevel($this->config->get("pos1")["level"]);
                $p->setLevel($this->getServer()->getLevelByName($this->config->get("pos1")["level"]));
                eval("\$p->teleport(\$this->pos".$i.");");
                unset($p);
            }

[dktapps]

You're seriously using eval()? wtf :facepalm:

[smlrrlms]

Its very old plugin and not my. On previous API its work and it suited me ...

[Muqsit]

In that case, contact the author requesting him to update the plugin.

[smlrrlms]

The author has long ceased its development. better tell me what error occurs or where to look.

[smlrrlms]

This occurs when the player clicks on a plate.

[Muqsit]

This isn't a support forum. Better not use the plugin if the author has abandoned it.
